问题 How to add any Component like a JButton on the JFrame TitleBar in java swing. 回答1: I assume by "title bar" you think of the header with the window menu button, document or program title and buttons for (typical) maximize, minimize, close. The window borders are drawn by the operating system (whatever part, e.g. with XServer it would be a window manager most of the time) - usually. And this is what the user wants - usually. Then this part of the window is outside the reach of Swing, you need

问题 My question is clear. Is there any way to restore the width of the columns automatically after user has resized them? Every time the button is clicked, I want the column widths to be restored. public class TableTest { public static void main(String[] args) { SwingUtilities.invokeLater(() -> { JFrame frame = new JFrame(""); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setLayout(new BorderLayout()); JTable table = new JTable(new Object[][] { { "something", "something else" } },

问题 When you set the icon for a Swing control (say a JButton ), a disabled icon with grayed-darker colors automatically generates. I want to be able to imitate the way the icon colors are changed for the disabled state, so I can create my own disabled icon with a little twist, and set it as the disabled button. Is there a way to achieve this (other then first instantiating the control and retrieving it's icon, I'm looking for more straight-forward less hacky way)? 回答1: Is there a way to achieve

问题 I'm arranging images in a grid with MigLayout. I could get the width to take the whole space available in the column, but then I want the height to grow accordingly so the proportion of the image still fixed. What is the best approach for this? Could I do that with an expression in the constraint or I have to override the getPreferredSize()? Thanks! 回答1: After a lot of researching, I realize that there is no nice way of doing this with Swing. The problem is not only coming from MigLayout but

问题 This question already has answers here : Limiting TextField inputs (2 answers) Closed 6 years ago . I figured this would be a simple search on the web but I can't figure this out. Here is what I'm working with so far. Ignore the eventHandler, I know its empty. I want to limit the charField JTextField so that the user can only type one character. I figured this would be easy because of all the apps that limit the amount of numbers you can type when entering State or Zipcode. To be clear, I'm
